We aren't going to move to Clang 13 in a hotfix release. The other
dependencies passed their postponement re-evaluation date, but also
won't be updated just yet.
- The patches `iostreams-106.patch` and `signals2-noise.patch` were
incorporated into Boost 1.75.
- The allocator access deprecation issue was fixed in Boost 1.76.
Closeszcash/zcash#4945.
This is the second release in a row where LLVM has cut a X.0.1 for
everything except Darwin, so I've adjusted its URLs and paths on the
assumption this will continue.
Bitcoin Core doesn't actually use tags for managing versions of their
forked dependencies, so we should separately rework this logic for all
of the subtree-managed dependencies. But this at least prevents false
positives.
Reduce default fee to 1000 zatoshis
Per ZIP 313. This also ensures that transactions that pay the default fee will always be relayed, and not rate-limited.
This removes the paches iostreams-106.patch and signals2-noise.patch
which have been incorporated into boost 1.75. Also, this further
postpones updates to native_clank, libcxx and native_ccache.
We don't currently have a need for newer releases, and will likely be
pinning Rust for longer periods of time once we are also pinning Clang.
Rust releases occur every six weeks, so we can pre-emptively postpone
releases through the end of this year.
- The old patch is no longer necessary because of this upstream fix:
https://github.com/boostorg/build/pull/560
- Boost 1.72 removed a <deque> from an include, which exposed a missing
include in src/httpserver.cpp.
- Boost 1.73 moved function placeholders into the boost::placeholders
namespace.
- The new patch is a fix from just after Boost 1.74 was released, fixing
a warning that was missed.
depends: Switch to `cargo vendor` for Rust dependencies
When we first integrated Rust into our build system, we had two
limitations:
- We were building the `librustzcash` FFI library as a dependency, and
therefore needed access to its crate dependencies in the depends
system.
- Gitian builds happen offline, so we needed to fetch any crate
dependencies ahead of time, and then configure cargo to use these in
an offline environment.
At the time, `cargo` already had support for "Source Replacement", but
there was no easy way to package the dependencies in the necessary way.
What we implemented was effectively the `cargo-vendor` tool, built using
Makefiles. A noticeable downside was that we were pinning dependencies
twice: once in the `Cargo.lock` for the FFI library, and again in our
depends system.
Since then, `cargo-vendor` has been upstreamed into `cargo` itself, and
we have moved `librustzcash` into this repository. We can therefore use
`cargo vendor` directly from our pinned Rust compiler to fetch the
dependencies, and rely on our local `Cargo.lock` to pin the specific
crates we are relying on.
Use the Rust tracing crate for C++ logging
This PR swaps in the `tracing` crate (via FFI) for logging to either standard
output or `debug.log`. It transparently maps all existing `LogPrintf` and
`LogPrint` invocations to info-level `tracing` events, and passes through
correct file and line information. `error` invocations are mapped to error-level
`tracing` events, currently without line information (due to the way that
`error` is used in the codebase; swapping individual callsites to the new
`LogError` macro will provide that information).
The end-goal for this change is that we don't need to make any disruptive
changes to the codebase, but we can start to leverage `tracing`-specific
functionality where we want to, such as providing extra fields on certain log
lines (that can be filtered for), adding spans to record the flow of execution
through `zcashd`, and logging within C++ and Rust simultaneously. Support
for extra fields on spans and events will be added in a subsequent PR.
The `-debug` config options are converted at launch into their corresponding
directives for tracing's `EnvFilter`. The new `setlogfilter` RPC method allows
this filter to be reloaded dynamically. The syntax is documented in the
`setlogfilter` help text, as well as here:
https://docs.rs/tracing-subscriber/0.2.7/tracing_subscriber/filter/struct.EnvFilter.html#directives
When `-printtoconsole` is specified, the output now includes timestamps and
ANSI encoding :)
A new safe_depends() checker is added, which allows the '.' character on
top of the existing safe() characters.
The time crate is postponed to 2021-02-01, by which time hopefully the
chrono crate will have figured out what it is doing with that dependency.
